Find the coordinates

Irina-Kira [14]

Answer:

The answer to your question is -3, 7

Step-by-step explanation:

Data

x + y = 4 ------------ Equation l

7x + 9y = 42 ----------- Equation ll

Process

1.- Solve the system by elimination

- Multiply equation l by -7

-7x - 7y = - 28

7x+9y = 42

2.- Simplify

0 + 2y = 14

3.- Solve for y

y = 14/2

y = 7

4.- Substitute y in equation l to find x

x + 7 = 4

Solve for x

x = 4 - 7

x = -3

Which of the following is another way to express the equation 8 - (-) = 43?

Olin [163]

Question:

Which of the following is another way to express the equation 8 - (-d) = 43?

A.8-d=43

B.-d+8=43

C.-8+d=43

D.8+d=43

Answer:

8 + d = 43 is another way to express the given equation

Solution:

Consider the given equation

$8 - (-d) = 43$

We have to find the another way to express the above equation

We know that,

We we multiply negative sign number by another negative sign number, then the result is positive sign number

Therefore from given,

$-(-d) = -1 \times -d = d$

Thus the given equation becomes,

8 + d = 43

Thus option D is correct

Simplify the following Square root 15 / Square root 3

Elina [12.6K]

Answer:

The answer is √5 .

Step-by-step explanation:

You have to rationalize the fraction in order to get rid of surd in the denorminator by multiplying √3 to both numerator amd denorminator :

$\frac{ \sqrt{15} }{ \sqrt{3} }$

$= \frac{ \sqrt{15} }{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} }$

$= \frac{ \sqrt{15} \times \sqrt{3} }{ \sqrt{3} \times \sqrt{3} }$

$= \frac{ \sqrt{45} }{3}$

$= \frac{ \sqrt{9 \times 5} }{3}$

$= \frac{3 \sqrt{5} }{3}$

$= \sqrt{5}$
